Hi Guys

Has anyone ever made wooden gears with the CW? I'm thinking it could be done with the DXF importer and something lime Mathias Wandell's Gear Generator (http://woodgears.ca/gear/index.html) application?

Would love to hear from people who have already done it? Can it be done without the expense of the DXF importer?

Cheers

wizer,
Yes you are on the right track. I did some work with a CAD program for another project, and it was doable, but the DXF importer will make things like this much easier. The biggest problem i ran into before DXF, is trying to get things to come out to scale. When processing it, and then importing into designer, it would loose the size. It was able to be overcome by drawing a square around your geometry and scaling it to bring it back, but it was somewhat of a pain.

The way i understand it the DXF importer will hold the scale, and give you the ability to cut out exact to a polyline that would be imported. This is a big shortcut to the way i did it a couple years ago. This should prove to be a very good piece of software!

Both CAD/CAM software packages that I use have a gear generator, and DXF export capability. All ready for the new software :)

Happy Carving!

A while ago I seen some one who was looking to make wood gears
for making a clock and I ran into this Gear template generator
(it's free) and this may help in making your gears.

Check it out here (http://www.woodgears.ca/gear_cutting/template.html)

This clock gear was made from a set of plans in DXF format.

I made a couple of gears using Gear template generator. Go to woodgears.ca than go down to gear template generator. this is a neet site.Ineed to work more to get them wright need time.:):)

hehe thanks for reccomending the gear generator by Mathais Wandell. Tho, I'm a bit worried about you guys, I mentioned this in my first post :lol:

petz29: When you say you made some, was that with the CarveWright? Or manually with a scroll saw?

Thanks Metallus, so how did you get the DXF model into designer? Did you do it with the importer or some other method?

Now that's impressive! :cool:

The new DXF importer, of course. I've also cut smaller gears from our 1/4" cast acrylic with the 1/16" cutting bit. I have also made a wooden bicycle cassette with the STL importer.

I made the gears using the carvewright . I used snipit to copy the gears & moved them to carvewright.

I have never used it, but I recall seeing a Sketchup plugin to draw gears. Then you could export them as an STL and use the STL Importer or the DXF importer.

Wizer,

I dabbled with making some wooden gears in the past and prototyped a clock (see thread http://forum.carvewright.com/showthread.php?t=9075&highlight=involute), although it required somewhere on order of ~7lbs of weight and would only run for an hour or so before. (The short run time was due primarily to wheel wobble, whereby the wheel would no longer contact the pinion, and the weight would race down.)

I recently began another project involving star toothed gears, and discovered that the Select Bit function was more accurate than the Cut Path function. Whereas the previous project involved the 1/8" cutting bit, this project is making use of the 1/16" cutting bit. (See http://forum.carvewright.com/showthread.php?t=12100&page=2). With the move to the Select Bit function, I'm really impressed with the capability of the CW.

Since the DXF importer didn't exist previously, I wrote a program to generate the gear profiles in the adobe illustrator (AI) file format, and use the ai2mpc program to convert them to MPC files.
